Now that the non-shop vapes are spawning, I realized that there are a ♥♥♥♥-ton of them hahah. Enough that they almost overpower regular weapons spawning.

My suggestion would be to add some convars for enabling/disabling some of the vapes so users can reign them in a bit. That's probably the easiest way. The downside of this approach being that you probably have to get rid of a few of the different versions of vapes entirely just for the sake of fewer overall vapes.

The alternative would be a convar setting to lower the overall number of vapes spawned, but I don't know how that would be done and is probably hard to do.

My apologies if this already exists and I just don't know about it.

Maybe it has to do with all the random spawnpoints you added for weapons? On Minecraftcity, barely any spawn.

Don't know if you're still working on this, but could you add something like a console command to make it so everyone spawns with one and they don't spawn on the map?
